Cat 5 cable totally sheathed in metallic foil, carrying data from a 64k cctv camera - can I run it alongside 220v AC…?

Thanks

I’ve seen many data centres with Cat cable co existing next to power in cable trays with no issues being reported.

Pedants corner here - it will be 230V AC here in France, or anywhere European homologised (if that’s a word). It’s supplied as 230V +/- 10%.

To answer the question, it will be no problem.

Finger too big … :grinning: I meant 230.

Thanks confirming the runs. Much said on the internet about separation, with one or two saying that with shielded cable it is ok.

I will add my last question in this post - a cctv POE camera, does it need surge protection? Again much on the internet yes and no…

I’d have thought that you’d want surge protection on the switch rather than the camera. If you need it at all, that is.

Can you explain surge protection please?

My situation is a small NVR that has in built POE. It will have two cameras connected to its POE sent out on [shielded] Cat5 cable./ The cable is in a conduit all the way to the cameras and the cameras are not earthed.

Will this act as a surge protector for the whole installation:

or do I need individual blocks on the two Cat5 cables…?

thanks
